Abstract
The appearance of gas bubbles in veins inside the body is the primary cause of decompression illness. Preliminary research has conducted to develop the gas bubble detection system in the both mediums of water and blood with an oxygen and nitrogen gas bubbles. In this research, we use a computer simulation approach based on the analysis of the ultrasonic signal alteration that was received by the transmission and reflection signal mode. The result shows that the attenuation is caused by the absorption of the medium was very small, which the reduction of the amplitude for the medium of blood and water, respectively 1.1% and 0.012%. The existence of gas bubbles within the medium drives the amplitude reduced by 4% to 5% from the initial amplitude and the intensity percentage that was reflected by the bubbles for the medium of blood is greater than the medium of water. The selected frequency of the ultrasonic signal source influences the ability to detect the diameter of the bubbles.
